Announcement to be made before release of "Highschool DxD" OVA

A new OVA anime episode is set to be released on September 20th, with volume 13 of Ichiei Ishibumi and Miyama-Zero's High School DxD light novels about a pervy highschool student revived after being killed by a fallen angel on his first date. However, leading up to that date, there's going to be an announcement about the series made on the 6th.

A 12 episode TV series ran at the beginning of this year, but there's still plenty of High School DxD that hasn't been animated, leading to speculation that another series might be on the way.
